Be it known thati, CHARLES S. MosELEY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Time-Stamps, of which the'following is a full, clear, concise, and eX- act description, reference being had to the accompanying drawings, forming a part of 1o this specification.

My invention relates to a time-stamp of the class in which an electromagnet mounted in the base of the time-stamp is adapted to be actuated at intervals by suitable controlling means-as, for instance, a clock-to thereby actuate the indicator mechanism of the timestamp. This indicator mechanism is usually carried upon the end Vof a swinging arm mounted upon the base or bed plate; and one zo of the objects of the present invention is to provide improved means for transmitting motion from the armature of the magnet to the time mechanism.

My invention further contemplates a num- 2 5 ber of improvements in .mechanical detail and arrangement, as will be more particularly set forth hereinafter.

l have illustrated my invention in the accompanying drawings, in which- Figure l is a plan or top view of the device of my invention. Fig. 2 is a vertical longitudinal sectional view. Fig. 3 is abottom view of the base or bed, showing magnet-.fastenings and electrical connections. Fig. 4 is a detail 3 5 `view of the indicator-wheels on the line 44,

Fig. 2. Fig. 5 is a' perspective view of the live pawls. Fig. 6 is a side view of block holding the detents. Fig. 7 is a verticallongitudinal section of a modification of my invention.

Like letters refer to like parts in the several figures.

In a metallic base or case a, is located an electromagnet b, which may consist of one or more spools, preferably two spools, as shown in the drawings, connected in circuit with the main regulator. mand iiush with the same is a platen a', preferably of rubber, having a canvas facing,

5o upon'which when a record is desired the paper or document to be stamped is placed.

Set into the top of the case The armature b' of magnet b is mounted on pivots b2, consisting of screws having recesses in the armature, so that the armature b' may vibrate with little friction'upon its pivots. '55 The pivots b2 arekept from workin g loose by set-screws 1912. The screw b3, which is threaded into and passes through arm b4, has ahalf ball or headV b5 on the end which engages a hemispherical recess or socket b in the lower 6o part b. The opening U( in armature b', through which screw b3 passes, is conically countersunk, so as to admit of a free swinging movement in recess b. The screw b3 is conically tapered as it passes through the countersunk opening o7. The orifice bs opposite the head end of screw b3 permits of the adjusting of the arm b4 by said screw. without removing any plates. The arm b4 is sawed or split at the lower end, thus per- 7o mitting it to grip the screw b3 when screw is tightened, so as not to allow screw b3 to work loose. The socket and spherical head permit the armature to freely swing while permitting the partial turning of the rod b3- 75 for adjustment without affecting the movement of the armature.

The means for fastening the magnets to the case a are as follows: The cores of the magnet b are turned down and threaded where 8o they pass through the yoke or cross-bar b9' and are firmly fastened to case c by nuts b1", which are screwed onto the cores of magnet b.

Mounted upon base a is a hollow rocking arm c. This arm is pivoted at its rear end, so that it may rock freely upon pivots c, (shown as4 consisting of screws extending through suitable orifices in lugs 02,) rising from the case cv. The forward end of the arm c supports an enlarged hollow cap, which fits 9o over an enlarged portion ot' arm c, forming a casing or head c3.Y The hollow cap may be 'emoved for the purpose of obtainingaccess' to the mechanism contained therein by re`- Y moving screws c4. The cap c3 carries a seat 9'5" into which is set a dome-shaped piece c5, of rubber, forming a cushioned handpiece or knob to be engaged by thel hand. The rubber piece c is in the form of a fiat disk, the edges of which are bent down to iit into the roo seat and to form the whole into a domeshaped structure. The swinging arm may be depressed by the handpiece c5, and a spring c6 retracts the same. The spring e6 is secured near one end to an arm c", which extends' downwardly from the rear end of arm c into the case a and at its other end to a support 08, extending from the top case a.

There are eight indicator-wheelsin all, six of which are operated to indicate changes in time bythe action of the electromagnet. The other two are operated by hand.

The six indicator-wheels which are operated by the action of the eleetromagnet are mounted side by side loosely upon a shaft d, which is journaled in'the side of an enlarged portion ot' rocking arm c, which lits inside of the hollow head c3. which are mounted on the shaft d, work independently of each other, motion being given to them by a number of live pawls d', d2, 3, d4, d5, and d6, which are mounted upon and form part of cross-bar 6K7. The cross-bar CZ? is provided at its ends with lugs d8, through which extends a rod 039, journaled at its ends in suitable bearings in side arms dloof a frame consisting of a stretcher-bar du, extending between the side arms d10 and secured to the latter at its ends. The side arms d10 are loosely hung at their inner ends upon the shaft cl inside the month-wheel g and the year-wheel g', which wheels are mounted on opposite ends of shaft d. The frame is therefore free to move up or down. A coiled spring e, coiled about the rod di and bearing at one end against the bar cZand at the other against the stretcher-bar du, tends to force the pawls d', d2, d3, d4, d5, and d6 toward the indicatorwheels. Each of the indicator-wheels is provided upon its periphery with raised type and upon one of its sides with a ratchet-wheel. The pawls c?, dac., in causing the rotation of the indicator-wheels operate upon the teeth of the ratchet-wheels. They are thus caused to operate by a swinging motion which is imparted to the frame carrying the pawls by means of a link e', pivotally connected at one end to the lever e2 and at the other to the rod (Z9 of the said frame. The indicator mechanism is well known in the art and does not in its individual capacity forma feature of my invention.

Mounted upon the shaft CZ is the monthwheel g and the year-wheel g', both of which are, operated by hand. Upon the respective indicator-wheels and acting in conjunction therewith are ratchetwheels, the teeth of which are engaged by the live pawls d d2, dac., and also by the deten ts e9 e9, to prevent backlash. The ratchet-wheel ot' the unit min` ute-wheel g2 has a deep depression into which pawl d2, which is of greatest length, drops after having engaged ninel of the teeth successively. The pawl d2 having dropped into said engagement allows the next longest pawl d3 to engage the ratchet-wheel on tens minute-wheel g3, the said ratchet-wheel also having a depression into which pawl cl3 drops every sixty minutes. When both pawls d2 These indicator-wheels,

d3 are in their respective depressions, the pawl d4 engages the teeth on the ratchet-wheel of hour-wheel g4, said ratchet-wheel also having a depression into which the pawl (Fdrops when the pawls above mentioned have dropped into their respective depressions, so thatevery twelve hours the two minute-wheels and the hour-wheel move together. When the three pawls referred to are in their respective depressions, th'e next longest pawl d engages the teeth of the ratchet-wheel of the a. m. and p. m. wheel g5, which wheel has six depressions, into one ot' which depressions pawl CZ drops every twenty-four hours. The teeth on the ratchet unit month-wheel g6 is next engaged byits pawl d5, and after having engaged nine teeth the pawl d5 drops into a depression on said ratchet-wheel. Next in order is the tens month-wheelgl', the teeth of the ratchet-wheel of said wheel being engaged every ten days.

The lever e2 is mounted upon a fulcrum e3, which is journaled in the walls of rocking arm c. The spring e4 is bent half around lug e5 and carried over the fulcrum e3 and then forward and under lever e2 and back over fulcrum e3 and over lug e5, andoperates to keep the forward end elevated and also to retract the armature b of magnet b after said magnet is denergized. The rear end of lever e2 is slotted to engage the lug e on lever e7. The lever e7 is also mounted upon a fulcrum es, which is journaled in the walls of rocking arm c. The upper end of arm h4 is pivoted to the lever e7 at approximately the same center of rotation as the rocking arm c, so that the rocking of arm c will impart no motion to levers e7 e2, link e', and pawls d d2, dre. When the eleetromagnet is energized and the arm 1941's pulled forward, the lever e7 is rocked on its joint, which causes the slotted end of lever e2 to be carried upwardly and the forward end of lever e2 to be moved downwardly, thereby causing link e to swing the frame carrying the pawls in a downward direction and moving said pawls far enough to cause one or more of them to engage teeth upon the ratchets of the indicator-wheels. the electromagnet is denergized, the spring e4 operates to move the lever e2, the link e',

rection, thereby causing a rotary progressive movement to be imparted to one or more 0E the indicator-wheels. Backward movement of the indicator-wheels during the rearward movement of the pawls is prevented bya number of detents e9, loosely hung upon a barf, secured to the walls of the enlarged portion of arm c. These detents engage the ratchetteeth upon the indicator-wheels and are so constructed as to exactly tit the space between the teeth, so as not to allow of any backlash or play. These detents are held in such engagement by coil-springs f', bearing upon their upper ends, which are secured in barf. Said bar fis secured at its ends to the enlarged portion of rocking arm c.

The tension of When A IOO IIO

these coil-springs is regulated by screws f2, which screws have counter-screws f3, which keep screws f2 from working loose. The enlarged portion of arm c has a face-plate h inserted in the under side thereof. Both edges of said plate are beveled, one edge iitting an overhanging shoulder orledge in the head and the other `side being held by the head of a screw h'. Said plate has an opening, so as to let the indicator-wheels print on the document. Upon this plate may be mounted such letters or combinations of figures and letters as may be desired, such as the name of kaneindividual or firm. By the removal of the screw h' the plate can be easily removed withouty disturbing the wheels. Any type mounted on plateh is in the same plane as the printing-type on the indicator-wheels.

Within the bed or base and depending from the upper wall thereof are thestandardsk 7c, which support the binding-posts. 'lhe standard is provided with an opening or bore, within which ts a shell la', of insulating material. Within this shell is arod kof conducting material, having openings in Vthe opposite ends for the reception of the conductors. Openings k3 k3 are'provided through'the wall of the base for the passageof the leading-in conductors. v Y

Fig. 7 shows a modification of my invention. Instead of using two levers inthe rocking arm c to operate the frame which carries the pawls I use buta 'single lever ew, with a rack e on the forward end, which engages a pinion cl2, which is mounted upon a shaft journaled in they sides of the head. Mounted upon the side of said pinion is'adisk h2, which carries a pin h3, upon which pin alink or connecting-rod is hung, which link is fastened to the pin di. When the armature is attracted by the magnet, the lever @loris rocked on its fulcrum cl3, thereby carrying the forward end up and causing the pinion toV rotate to the right, thereby causing the link to impart a downward movement of pin d. The spring h4 retracts the lever el", thereby causing the same movement as described in thek other invention. By employing the rack and pinion the rocking frame which carries the live pawls is caused to start in motion gradually and is gradually brought to rest, due to thefact that the rocking frame is connected with the crankpin, which during the semirevolution of the pinion imparts motion to the rocking frame by gradually starting the same and then moving the same at a greater speed and gradually bringing the same to rest at the end of the travel, the movement being similar to that of the crank-pin of a steam-engine. The sudden movement of the indicator-wheels and the consequent derangement or msplacement that might follow therefrom is thus effectually avoided.
